Nitrogen recycling - the key to circular economy

The project aims at testing and evaluating a concept in pilot scale for recycling of nitrogen from sludge from sewage treatment plants. Today there is no commercially available technology that extracts nitrogen from wet residues in a clean, solid and highly concentrated form. The project will evaluate the performance of the pilot plant, including nitrogen separation, product quality, and chemical consumption.
